The flaw that Jani found “would have impacted everybody on Instagram” said to the media Melanie Ensign, a security representative at Facebook. After Jani discovered the bug and told Facebook about the problem, the company created a test Instagram account and posted a comment. All right, Facebook told him, go delete the comment. So he did it. The most interesting part is that Jani’s hack did not require him to sign in or even create an account. If he hadn’t made an account he may have forfeited his claim for a reward. Jani and his brother had a habit of watching videos about computer security on YouTube. Nobody asked but possibly they are preparing to become computer scientists.
